Description

Technical Field

[0001] This invention belongs to the field of garbage truck technology, and specifically relates to a garbage truck with compression function. Background Technology

[0002] With the acceleration of urbanization, the amount of domestic waste generated is increasing day by day, and the efficiency of waste collection and transportation has become an important part of urban environmental sanitation management. Traditional garbage trucks mostly use manual or semi-automatic methods to lift, empty, and load garbage bins, which has problems such as high labor intensity, low efficiency, large amount of garbage residue, and easy emission of odors.

[0003] Most garbage trucks currently on the market only have simple lifting and dumping functions, and cannot compress garbage during collection, resulting in limited loading capacity and high transportation costs. Furthermore, garbage bins often require manual opening during dumping, which is cumbersome, has low automation, and is not suitable for widespread use. Therefore, there is an urgent need for a garbage truck that can achieve continuous automated operation of lifting, opening, and dumping, while also possessing garbage compression capabilities. A patent with publication number CN118062446A discloses a garbage truck bin lifting and tilting device. This device includes a guide rail, a slide, a top gear, a first gear, a second gear, a third gear, a first cylinder, a first rotating shaft, a second rotating shaft, a lever, a handle, a lifting plate, and a pin. In use, the guide rail drives the slide to rise, causing the top gear to engage between the reinforcing ribs of the garbage bin, thus lifting the bin until the first and third gears mesh. Subsequently, the first cylinder pushes the first rotating shaft to slide within a sliding sleeve, causing the lever to engage below the handle. Then, an electric push rod drives the lifting plate and the pin to rotate, tilting the garbage bin. Simultaneously, the rotation of the pin drives the first gear, which in turn drives the third and second gears to rotate synchronously. The second gear, through the second rotating shaft, drives the swing arm to rotate, which in turn drives the swing arm and the lever to rotate in the opposite direction via a sprocket and chain, opening the top cover.

[0004] However, the above solution requires several steps when emptying the trash can. First, the electric push rod needs to be activated to rotate the trash can after it reaches a certain height. Second, the first cylinder needs to be pre-controlled to push a lever into the handle so that the top cover opens simultaneously during the tilting process, completing the emptying. This process is cumbersome and relies on the coordinated control of multiple independent drive sources, resulting in significant operational interruptions and a lack of continuity. This significantly reduces the efficiency of trash emptying and hinders its practical application. Summary of the Invention

[0008] Furthermore, the lifting cover assembly includes a first connecting rod, with the first connecting rod fixedly installed on both sides of the top plate, and a push block fixedly installed on the top of each first connecting rod for transmission cooperation with the upper cover.

[0009] Furthermore, the limiting component includes a second limiting block, a guide shell is fixedly disposed on the sliding seat, and the second limiting block is slidably inserted into the guide shell; the first connecting rod is provided with an insertion hole opposite to the guide shell in transmission, and the second limiting block both supports and limits the first connecting rod, and also engages with the insertion hole in transmission.

[0010] Furthermore, the flipping assembly includes a second connecting rod and a roller shaft; the second connecting rod is rotatably arranged on both sides of the sliding seat, and the same roller shaft is rotatably arranged between the two second connecting rods, and the roller shaft is in contact transmission cooperation with the trash can; a first limiting block for limiting the angle of the second connecting rod is also fixed on the sliding seat.

[0011] Furthermore, the transmission component includes a gear and a rack; the gear is fixedly sleeved at the rotatable connection between the second connecting rod and the sliding seat, and the rack is fixedly disposed on the outer surface of the truck bed; when the sliding seat rises to a set height, the gear and the rack mesh and transmit power.

[0012] Furthermore, a baffle is fixedly provided on the top of the top plate, and a slot is opened on the inner side of the edge of the baffle. The top of the trash can is provided with a plug that cooperates with the slot.

[0013] Furthermore, the power mechanism includes a second hydraulic rod; two first connecting plates are rotatably arranged inside the truck bed, and the other ends of the two first connecting plates are rotatably connected to a second connecting plate, and the two second connecting plates are rotatably connected to the back of the pressure plate; the two first connecting plates are connected by a first fixing rod, and the two second connecting plates are connected by a second fixing rod; one end of the second hydraulic rod is hinged to the first fixing rod, and the end of its telescopic shaft is hinged to the second fixing rod.

[0014] Furthermore, a guide block is fixedly provided on the outer surface of the pressure plate, and a guide groove is provided on the inner wall of the truck bed to limit and slide with the guide block; a guide rod is fixedly provided on the pressure plate, and the cleaning block is slidably sleeved on the outer surface of the guide rod.

[0015] Furthermore, the loading port and discharge port of the truck bed are respectively rotatably sealed by a first opening and closing plate and a second opening and closing plate; the truck bed is provided with a first closing mechanism acting on the first opening and closing plate and a second closing mechanism acting on the second opening and closing plate; the first closing mechanism includes a first motor, a worm gear fixed to the output shaft of the first motor, and a worm wheel coaxially fixed to the first opening and closing plate and meshing with the worm gear; the second closing mechanism includes a first hydraulic rod, the two ends of which are respectively hinged to the truck bed and the second opening and closing plate.

[0016] This application has the following beneficial effects: 1. As the drive mechanism raises the top plate to lift the trash can, the lid-lifting assembly on the top plate automatically opens the lid, improving the automation level of waste collection and reducing manual intervention. Subsequently, as the trash can continues to rise, the tilting assembly automatically rotates with the assistance of the transmission components, thereby tilting the trash can to achieve automatic waste dumping. This process is simple to operate, with smooth and continuous movements, and does not rely on the coordinated control of multiple independent drive sources, significantly improving the efficiency of waste dumping and making it more suitable for practical application.

[0017] 2. When the trash can is tilted, it can slide under the action of gravity and collide with the baffle, creating a slight vibration. This promotes the dislodgement of trash inside the can, thereby improving the dumping effect and making it more practical.

[0018] 3. This application uses a power mechanism to drive the pressure plate to reciprocate within the truck bed, which can compress the collected garbage, effectively improve the space utilization of the truck bed, increase the single loading capacity, and reduce the frequency of transportation and operating costs.

[0019] 4. When unloading garbage from the truck bed, the power mechanism drives the pressure plate to move towards the second opening and closing plate. When the pressure plate moves to the set position, the rope gradually tightens and pulls the cleaning block to slide along the surface of the pressure plate, thereby scraping off the garbage with strong adhesion to the surface of the pressure plate, reducing the difficulty of manual cleaning, facilitating the subsequent washing of the inside of the truck bed, and further improving the practical effect of this application.

[0020] 5. After the second limiting block is inserted into the guide shell through the insertion hole, the lateral cross section of the vehicle body in the driving state can be significantly reduced, which is beneficial for the vehicle to pass through narrow roads and improves the overall passability and operational safety.

[0021] 6. This application achieves the compression and unloading of waste through the horizontal movement of the pressure plate within the truck bed, eliminating the need for the lifting and dumping method of traditional garbage trucks, thus significantly improving operational flexibility and spatial adaptability. This design is particularly suitable for operating environments with height restrictions or confined spaces, solving the problem that traditional garbage trucks cannot enter certain scenarios due to vehicle lifting. Simultaneously, it avoids the risk of tipping over caused by raising the vehicle's center of gravity due to lifting the truck bed, improving operational safety and stability.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0025] like Figures 1-17 As shown, the technical solution adopted by the present invention is as follows: a garbage truck with compression function includes a vehicle body 1 with a truck bed 2 and a garbage bin 8 with a top cover 9 that is rotatably provided. A loading port (not labeled in the figure) is opened on the top side of one side of the truck bed 2, and a discharge port (not labeled in the figure) is opened on the rear side of the truck bed 2.

[0026] The loading port of the hopper 2 is provided with a first opening and closing plate 3, which is rotated and sealed. The hopper 2 is provided with a first closing mechanism that acts on the first opening and closing plate 3.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, the first closing mechanism includes a first motor 10, the first motor 10 is fixedly installed on the top of the truck bed 2, and the output shaft of the first motor 10 is fixedly provided with a worm gear 11; a worm wheel 12 is fixedly provided at the rotatable connection between the first opening and closing plate 3 and the truck bed 2, and the worm wheel 12 meshes with the worm gear 11 for transmission.

[0028] The discharge port of the hopper 2 is provided with a second opening and closing plate 4 for rotational sealing, and the hopper 2 is provided with a second closing mechanism that acts on the second opening and closing plate 4.

[0029] Specifically, the second closing mechanism includes a first hydraulic rod 5, which is rotatably mounted on the truck bed 2, and the telescopic shaft of the first hydraulic rod 5 is rotatably connected to the second opening and closing plate 4.

[0030] Among them, a connecting shell 6 is fixedly installed on one side of the loading port of the truck bed 2. The connecting shell 6 is equipped with a sliding seat 21 that is limited and slidable in the vertical direction, and a driving mechanism that acts on the sliding seat 21.

[0031] The sliding seat 21 has a top plate 15 that rotates and cooperates with the lifting of the trash can 8, and a limiting member that acts on the top plate 15. The top plate 15 is fixedly equipped with a lid lifting assembly that is in transmission cooperation with the upper cover 9.

[0032] Specifically, such as Figure 7 As shown, the drive mechanism includes threaded rods 25. Two threaded rods 25 are rotatably arranged vertically inside the connecting shell 6, and the two threaded rods 25 are connected by a chain drive assembly 27. A sliding seat 21 is threaded onto the outer surface of the two threaded rods 25. A second motor 26 is fixedly installed at the bottom of the connecting shell 6, and the output shaft of the second motor 26 is coaxially fixedly connected to the bottom of one of the threaded rods 25. The drive mechanism can control the lifting and lowering of the sliding seat 21 and the top plate 15. During the lifting process, the top plate 15 will cooperate with the reinforcing ribs of the trash can 8, thereby lifting the trash can 8.

[0033] Specifically, such as Figure 6 As shown, the lifting cover assembly includes a first connecting rod 7. The first connecting rod 7 is fixedly installed on both sides of the top plate 15. Two push blocks 20 are fixedly installed on the top of each first connecting rod 7. The push blocks 20 are in transmission cooperation with the upper cover 9.

[0034] Specifically, such as Figure 5 As shown, the limiting component includes a second limiting block 22, a guide shell 24 is fixedly provided on the sliding seat 21, the second limiting block 22 is slidably inserted into the guide shell 24, and a snap-fit ​​component acting on the second limiting block 22 is provided in the guide shell 24. The first connecting rod 7 has an insertion hole 23 that is opposite to the guide shell 24 in transmission. The second limiting block 22 not only supports and limits the first connecting rod 7, but also engages with the insertion hole 23 in transmission. (It should be noted that the chain drive assembly 27 and the snap-fit ​​assembly in this application are conventional prior art, and this application does not make specific descriptions of them.) The sliding seat 21 is rotatably equipped with a tipping component that is in transmission cooperation with the trash can 8, and the outer surface of the truck bed 2 is provided with a transmission component that is in transmission cooperation with the tipping component.

[0035] Specifically, such as Figure 4 As shown, the flipping assembly includes a second connecting rod 16. The second connecting rod 16 is rotatably mounted on both sides of the sliding seat 21. A common roller 19 is rotatably mounted between the two second connecting rods 16, and the roller 19 is in contact with the trash can 8 via a transmission mechanism. The second connecting rods 16 drive the roller 19 to rotate, thereby achieving the rotation of the trash can 8.

[0036] More specifically, a first limiting block 18 is fixedly installed on the outer surface of the sliding seat 21, and the first limiting block 18 is used to limit the second connecting rod 16.

[0037] Specifically, the transmission components include a gear 17. The gear 17 is fixedly sleeved on the outer surface of the rotatable connection between the second connecting rod 16 and the sliding seat 21. A rack 13 is fixedly installed on the outer surface of the bucket 2. The gear 17 and the rack 13 engage in a contact-type meshing transmission. Through the cooperation of the gear 17 and the rack 13, the second connecting rod 16 drives the roller shaft 19 to rotate, thereby contacting the garbage can 8 to achieve the tilting of the garbage can 8.

[0038] Additionally, a baffle 14 is fixedly installed on the top of the top plate 15, with a slot (not shown in the figure) opened on the inner edge of the baffle 14. A plug that engages with the slot is fixedly installed on the top of the trash can 8. When the trash can 8 is rotated to an inclined state, it will slide and collide with the baffle 14, generating vibration. The baffle 14 is used to limit the tilted trash can 8 to improve the efficiency of trash dumping. At the same time, the cooperation between the plug and the slot further ensures the stability of the trash can 8 during the dumping process.

[0039] Furthermore, a fixed shaft 28 is fixedly installed at the loading port of the truck bed 2 to cooperate with the upper cover 9. The fixed shaft 28 is used to ensure that the upper cover 9 is in the open state.

[0040] In addition, the truck bed 2 is equipped with a pressure plate 36 that is slidably fixed in the horizontal direction, and a power mechanism that acts on the pressure plate 36 is also provided; a cleaning block 37 is slidably fixed in the vertical direction on the surface of the pressure plate 36, and a rope 35 is provided between the cleaning block 37 and the truck bed 2.

[0041] Specifically, such as Figures 15-16As shown, the power mechanism includes a second hydraulic rod 32, two first connecting plates 30 are rotatably arranged inside the truck bed 2, and a second connecting plate 34 is rotatably arranged at the other end of each of the two first connecting plates 30. Both second connecting plates 34 are rotatably connected to the back of the pressure plate 36. The two first connecting plates 30 are fixedly connected by a first fixing rod 31, and the two second connecting plates 34 are fixedly connected by a second fixing rod 33; a second hydraulic rod 32 is rotatably mounted on the first fixing rod 31, and the telescopic shaft of the second hydraulic rod 32 is rotatably connected to the second fixing rod 33.

[0042] More specifically, a guide block 29 is fixedly installed on the outer surface of the pressure plate 36, and a guide groove 39 is opened on the inner wall of the truck bed 2 to slide and limit the guide block 29.

[0043] More specifically, the pressure plate 36 is provided with a guide rod 38 that acts on the cleaning block 37. The cleaning block 37 is slidably sleeved on the outer surface of the guide rod 38, and the cleaning block 37 has a certain weight.

[0044] It should be noted that the accompanying drawings in this application are all structural schematic diagrams, and their specific sizes may be adjusted according to actual use.

[0045] Working principle: When using it, observe... Figure 2 At this point, push the trash can 8 towards the vicinity of the truck bed 2, and make one side of the trash can 8 abut against the top plate 15. Observe... Figure 9 and Figure 10 It can be seen that the first connecting rod 7 will not cause motion interference to the pushing of the trash can 8, so that the trash can 8 can be smoothly pushed between the two first connecting rods 7.

[0046] Subsequently, the first motor 10 and the second motor 26 are started. The output shaft of the first motor 10 drives the worm gear 11 to rotate, thereby driving the first opening and closing plate 3 to rotate through the meshing of the worm gear 11 and the worm wheel 12, thus opening the loading port of the hopper 2.

[0047] The output shaft of the second motor 26 drives the threaded rod 25 connected to it to rotate, and the chain drive assembly 27 drives the two threaded rods 25 to rotate synchronously, thereby driving the sliding seat 21 to move upward along the connecting shell 6. The sliding seat 21 drives the top plate 15 and the lifting cover assembly (first connecting rod 7 and push block 20) ​​on it to rise together.

[0048] In the initial stage of ascent, due to the length design of push block 20 (reference) Figure 9 The pusher 20 first abuts against the hinge of the upper cover 9 of the trash can 8, pushing the upper cover 9 to flip to a vertically open position, completing the automatic opening. Afterwards, the top plate 15 contacts the reinforcing ribs on the side of the trash can 8, beginning to lift the trash can 8 (see reference). Figure 11 ).

[0049] As the sliding seat 21 continues to rise, the trash can 8 is raised to a predetermined height. At this time, the gear 17 fixed on the second connecting rod 16 engages with the rack 13 fixed on the outer surface of the truck bed 2. As the sliding seat 21 continues to rise, the gear 17 rotates along the rack 13, forcing the second connecting rod 16 to rotate around its hinge point with the sliding seat 21, thereby driving the roller 19 to push the trash can 8 to tip over.

[0050] When the trash can 8 is tilted beyond a horizontal position, under the influence of gravity, it slides along the surface of the baffle 14 and collides with the edge of the baffle 14, generating a slight vibration to improve dumping efficiency and ensure dumping effect. The fixed shaft 28 ensures that the top cover 9 remains open during dumping, avoiding interference (see reference). Figure 14 ).

[0051] After the garbage is poured into the truck hopper 2, the output shaft of the second motor 26 reverses, causing the sliding seat 21 to descend and reset. The second connecting rod 16 drives the roller shaft 19 to rotate and reset under the meshing of the gear 17 and the rack 13, so that the garbage bin 8 returns to a vertical position. That is, when the sliding seat 21 moves to... Figure 2 After the state is reached, the top cover 9 will close again, and the emptying process of the trash can 8 will repeat as described above.

[0052] After the subsequent dumping is completed, the second hydraulic rod 32 is activated to control the extension of the telescopic shaft of the second hydraulic rod 32, which pushes the linkage mechanism composed of the first connecting plate 30 and the second connecting plate 34 to move, thereby driving the pressure plate 36 to move under the constraint of the guide block 29 and the guide groove 39, so as to compress the garbage in the truck bed 2 and significantly improve the effective loading volume of the truck bed 2.

[0053] After the garbage collection is completed, the second limiting block 22 can be pulled out from the guide shell 24, causing the first connecting rod 7 to flip downwards so that the insertion hole 23 corresponds to the guide shell 24. Then, the second limiting block 22 can be inserted into the guide shell 24 through the insertion hole 23 to lock it in place (see reference). Figure 1 This operation reduces the lateral extension of the vehicle while it is in motion, improving its maneuverability and operational safety on narrow roads.

[0054] When it is necessary to unload the garbage from the truck bed 2, the second opening plate 4 is first opened by the first hydraulic rod 5. Then, the pressure plate 36 is driven to move towards the second opening plate 4 by the second hydraulic rod 32, so that the compressed garbage is pushed out of the truck bed 2 as a whole.

[0055] When the pressure plate 36 moves to the end and approaches the right side of the truck bed 2 (see reference) Figure 15The rope 35 connecting the cleaning block 37 and the inner wall of the truck bed 2 is taut. As the pressure plate 36 continues to move forward, the rope 35 pulls the cleaning block 37 to slide upward along the guide rod 38, thereby scraping off the heavily adhered garbage on the surface of the pressure plate 36, reducing the difficulty of subsequent manual cleaning and facilitating the washing of the interior of the truck bed 2. Subsequently, the cleaning block 37 can automatically reset under the action of gravity.

[0056] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
